Preheat the Oven: Preheat your oven to 375°F (190°C). Prepare a 9-inch pie crust (store-bought or homemade), placing it in a pie dish and crimping the edges.
Prepare the Apple Filling: Peel, core, and slice about 4 medium apples (Granny Smith or Honeycrisp work well).
Prepare the Pecan Filling: In another bowl, mix 1 cup of pecan halves, 3/4 cup of light corn syrup, 1/2 cup of brown sugar, 1/4 cup of melted butter, 1 teaspoon of vanilla extract, and 2 large eggs. Stir until fully combined.
Layer the Filling: Pour the apple mixture into the prepared pie crust, spreading the apples evenly. Then, carefully pour the pecan filling over the apples, spreading the pecans evenly on top.
Bake the Pie: Place the pie in the preheated oven and bake for 50-60 minutes. Check the pie halfway through; if the crust edges are browning too quickly, cover them with aluminum foil.
Cool the Pie: Remove the pie from the oven and allow it to cool for at least 2 hours to let the filling set properly.
Serve and Enjoy: Slice your apple pecan pie and serve with a scoop of vanilla ice cream or a dollop of whipped cream for extra indulgence. Enjoy the sweet, nutty, and fruity combination!
